CHECK-CONTROLLED LIQUID-DISPENSING APPARATUS.

Application filed December 4, 1913.

To all whom it may concern Be it known that T, CHARLES S. BATDORF, acitizen of the United States, and a resident of Brooklyn, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Check- Controlled Liquid-Dispensing Apparatus, of whichthe following is a specification.

The invention pertains more particularly to apparatus by means of whichpredetermined quantities of a liquid may be discharged from onecontainer .to another or from a reservoir owned by a dealer into a tankor other receptacle owned by a customer or purchaser, or into a tank orrecep tacle to be emptied into a tank or receptacle owned by apurchaser.

The invention is intended more particularly, though not exclusively, forthe use of garages and dealers who supply, as a part of the businesstransacted, predetermined quantities of gasolene and oil to owners ofautomobiles, and one purpose of the invention is to provide suitablemeans whereby in the sale of gasolene or other liquid, both the dealerand purchaser may have a positive assurance that the predeterminedquantity of the liquid purchasedhas been delivered, and

also whereby in the sale and delivery of the gasolene or other liquidthe dealer, having possibly a number of employees, may ascertain whosold the gasolene and also the quantity sold, to-wit, the number ofgallons during, say, any predetermined interval.

At the present time the owner of garages and places where gasolene issupplied to owners of, automobiles, have means for deliveringpredetermined quantities of gasolene to owners of automobiles, but thesemeans are subject to the intelligence, will. and faithfulness, as wellasthe carelessness, of employees, and it frequently happens that aperson purchasing, say, three gallons of gasolene will not receive thatquantity but sometimes, due to carelessness or other reason, either lessthan that than that quantity.

My invention compels the accurate delivery of the predetermined quantityof liquid ordered, it being impossible to continue the apparatus of myinvention in use except quantity or more upon the delivery to apurchaser of the exact quantity of gasolene or the like ordered by him.Both the dealer and the purchaser may. therefore, always have theassurance of their business being transacted fairly, the.

Specification of Letters Patent.

Patented Apr. 13-, 1915. Serial 110,804,560.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

Figure 1 is an end view, partly broken away and partly in section, of amachine embodying my invention; Fig. 2 is a front elevation, artlybroken away and partly in substantially central vertical section, of thesame; Fig. 3 is a top view, partly broken away and partly in transversesection, of the same, and Fig. 4 is a view, partly broken away andpartly in vertical section, illustrating the application of my inventionto a container for delivering a predetermined quantity of gasolene orother liquid at each complete operation. of a plunger therein, theapparatus shown, aside from the features of my invention, being of knowncharacter and commonly used for delivering predeterminedquantities ofgasolene from one container to another. I

In the drawings 10 designates the main casing inclosing the noveloperative features of my invention, 11 a shaft extending through saidcasing and having on one end a crank handle 12 for its manual operation,

- 13 a pinion Wheel on the other end of said shaft, 14 a verticalplunger rod or rack-bar engaged by said pinion wheel and operablevertically therefrom, 15 a plunger secured on the lower end of said rodor bar and hav-' ing an upwardly opening valve of usual character.controlling a port therethrough, 16 a cylinder within which is formed achamber of predetermined capacitv as one gallon liquid measure, withinwhich the plunger 15 has its movement and which is provided at one endwith inlet ports 17 for gasolene or the like, 18 a liquid discharge pipeleading from the top of the cylinder 16 for dispensing the liquid inpredetermined charges to any container intended to receive it, and 19 acontainer supporting the casing 10 and inclosing the cylinder 16 andadapted to contain the gasolene or other liquid .in bulk to be dispensedin accurate quantities with the use of my invention, the container 19,cylinder 16, plunger 15, and

discharge pipe 18 being of known character.-

I The casing has ilat'sides, a rectangular lower front portion of thecasing 10, its.

lower portion, and a semi-circular upper portion formed by asemi-circular plate hinged at one ede, at 21, to the main body of thecasing. it the front of the lower portion of the casing 10 is provided aremovable door 22 equipped with a suitable lock 23 and at its lower edgehavin studs 24 to enter recesses formed in the bottom of the casing 10.The door 22 will be removed when it is desired to remove the tokens fromthe chamber 25 formed within the lower portion of the casing 10, andsaid door may be of any convenient form and construction and secured inany convenient manner. When the door 22 is in position closing the upperedge overlaps the front lower edge P of the semi-circular top 20andlockssaid top in its closed position.

The upper end of the casing 10is provided with an entrance26 for disksor the like constituting keys, checks or tokens, one ofwhich is shownand numbered 27, by which the apparatus may be operated, and in theabsence of which the apparatus is rendered inoperative. The casing 10may.

be of any suitable outline and through it extends the shaft 11 which iscommonly employed in connection with the container 19 for operating theplunger-rod 14. One side of the casing 10' is plain and flat andcontains no features on its exterior of any special moment, and theother side of the casing 10 is formed of. the plate 28 and a disk 29,said. disk being provided with the crank handle 12 and free to berotated on 'the shaft 11 or on a sleeve 30 which may be provided on saidshaft in the event that the shaft, as originally constructed, requiresto have a larger diameter in order to properlv receive the casing 10.The disk 29 on its periphery is recessed, as shown in Figs. 1 and 2 toreceive the surrounding portions of the plate 28, a shoulder 31 beingformed, on the disk to' match the edge 32 of the open- .ing in the plate28 which receives said, disk.

The disk 29 is held upon the shaft 11 or on the sleeve 30, as the casemay be, by means of a collar 33 fitting on the end of saidshaft' andfastened thereto in any suitable way, as by means of a screw or pin 34.

vWithin the casing 10 is provided a rotary frame 35 which has an outerdrum-like portion 36 and an inner externally threaded sleeve 37 thelatter fitting closely on the sleeve 30 and receiving an internallythread- 'ed frame 38 to be hereinafter referred to and which during theoperation of the machine has a traveling movement imparted to it towardand from the par't 36 of the frame 35. During the rotation of the sleeve37, the frame-38 has no -rotary movement but only a traveling movementback i and forth on the sleeve 37, said frame 38 tion of the slot todirect the keys or checks therefrom'when the same are released todescend against said portion 44. One side of theslot 41 is entirel open,so far as the frame 35 is concerned but there at is provided a pivotedarm 45 by which, during proper periods, the key or check 27 is heldwithin the slot 41. At the side of the slot 41 opposite to the arm 45and slightly above the upper end of the curved discharge chute 44, thedisk 29 is formed with a shoulder 46 to coiiperate with the arm 45 insupporting the key or check in the upper portion of the slot 41, saidshoulder 46, however, being of such slight proportions as to allow thekey or check 27 to at once descend through the slot 41 after the arm 45has been relieved from it. Those portions of the frame 35 at theopposite sidesof the slot 41 and which I designate as walls .42, 43,are' preferably of substantial thickness, as

. shownby the dotted lines in Figs. 1 and 3,

and have formed in them a through slot 46 which is on the arc of acircle, the slot being continued through the part 42 to the slot 41 andthen from the slot 41 through the part 43,.and this slot 46 is in linewith the normal location for the key or check 27 when the machine is inoperation and also in line with an arm'47 which is integral with thedisk 29 and projects inwardly therefrom. The arm 47 is slightly less inlength and thickness than the like dimensions of the slot 46 and may,when the disk 29 'is rotated without a key or check 27 being therein,freely pass through said slot. In' the initial position of the parts ofthe machine preparatory to receivlng through the entrance opening 26 akey or check 27 the arm 47 will stand within that portion of the slot 46within the wall 42 of the frame 35, in which position it is shown inFigs. 1 and 3, and then when a key or check 27 is introduced through theopening 26 to the slot 41 of the frame 35 and is arrestedat theposition-shownin Fig. 2, the arm 47 on the rotation of the disk 29' bymeans of the crank 12, will be carried against said key or check andthrough the latter compel the frame 35 to rotate, said key or check 27at such time barring the entrance of the arm 47 to that portion of theslot 46 within the wall 43. The key or check 27 thus 00-' operates withthe arm 7 as the medium; in.

' plunger 15 in the cylinder 1,135,2a1 I at the operation of themachine, for connecting the disk 29 with the frame 35. After the frame35 and disk 29 have rotated together during the requisite period, thekey or check 46 will be released, in the manner hereinafter described,from the slot Hand descending through the same will be directed into achute 48 extendinglaterally over the shaft 11 and then downwardly to thechamber 25 within which the keys, checks or other tokens may becollected and from which they may be removed from time to time as theowner of the machine may desire. The frame 35 is fastened to the shaft11 by means of a screw or pin 9 or otherwise, and the disk 29is-normally free on said shaft but rotates therewith when the arm 47 isagainst a key or check 27 held in the frame 35, and also during thereverse rotation of the disk 29, after the predetermined quantity ofgasolene has been delivered and the key or check 27 has been releasedand descended to the chute 48. During the rotation of the disk 29 in onedirection the arm 47 engaging the key or check 27 connects said disk andframe 35, and at this time a pawl 49 connected with the frame 35 ridesalong with, without specially or necessarily a ratchet tooth formed on aring 51 fastened to said disk 29, and during the rotation of the disk 29in the reverse direction, after the key or check 27 has left the slot41, the ratchet tooth 50 connected with said disk will press against theend of the 'pawl or dog 19 and by cause the frame 35 to rotate with saiddisk and become restored to its initial position with the slot 41directly below the entrance slot 26 in the main casing.

It may be mentioned here as a part of the operation of the machine thatwhen the frame 35 is in its initial position prepara-' tory to receivingthe key or check 27, the 9 16 will be it the bottom of said cylinder,and that said cylinder above the plunger will contain a predeterminedquantity of liquid, such as gasolene, and that after the key or check 27has been introduced to the frame 35 the disk 29 will through the handle12, be rotated to carry the arm 47 against the key or check 27 andeffect the rotation of the frame 35 and thereby the shaft 11 and throughsaid shaft and intermediate parts cause the plunger 15 to ascend anddischarge such predetermined quantity of gasolene or the like throughthe discharge pipe 18, this discharge being effected by the upward move-1 ment of the plunger 15 to the upper end of the cylinder 16. Upon thedischarge of the predetermined quantity of gasolene or other liquid, theframe 35 will have made a complete rotation, ordinarily, and by themeans hereinafter explained, the key or check 27 at all acting against,

through the same and there will have been released and descended to thechute 48. In the construction presented the plunger 15 will, at thistime, however, be at the upper end of the cylinder 16, and must bereturned to the lower end of said cylinder in order that the liquid mayflow above the plunger for the next sale or delivery, and to accomplishthis result the disk 29 is rotated in a reverse direction so that theshaft 11 may, through the pinion 13 and rod 14, cause the v the cylinder16. Since at this time the key or check 27 is not within the frame 35and since the disk 29 is not directly connected with the shaft 11, Iprovide the ratchet tooth 50 on the ring 51 fastened to the disk 29 sothat it, acting against the pawl 49,

may rotate the frame 35 and through said frame the shaft 11. The arm 17connected with the disk 29 coiiperating with the key or check 27 servesto rotate the frame 35 in one direction, and the ratchet tooth 50 inconnection with the pawl or dog 49, serves to communicate the reverserotation of the disk 29 to the frame 35 and through said frame to theshaft 11 for effecting the descent to its initial normal position of theplunger 15 in the cylinder 16. During the rotation of the disk 2-9 andframe 35 to effect the discharge through the pipe 18 of a predeterminedquantity of gasolene or the like, the pawl or dog 49 performs no dutybut simply travels with the ratchet tooth 50. When the disk 29 and frame35 are in rotation with the key or check 27 in position insaid frame, acomplete rotation of the frame is compelled from the fact that the keyor check projects slightly outwardly beyond the periphery of the frame35, as shown in Fig. 2, and that on the inner wall of the main casing 10is secured a series of spring dogs 8 which incline laterally and attheir lower ends are within a groove 52 formed in said frame 35 andextending entirely around the periphery thereof. During the rotation ofthe shaft 11, disk 29 and frame 35 to discharge a predetermined quantityof gasolene or the like, the spring dogs 8 perform no special functionand being yielding permit the key or check 27 to ride below them, but onany attempt to re verse the rotation of the disk 29 and frame 35 beforethe full quantity of gasolene has been discharged from the cylinder 16,the projecting edge of the key or check 27 will be carried against theend spring dogs 8 and thereby said disk and frame will be arrested intheir attempted reverse rotation. After the disk 2 and of one oftheplunger 15 to descend within 7 frame 35 have made a complete rotationin the proper direction to discharge the full quantlty of gasolene fromthe cylinder 16, the key or check 27 will have returned to its initialposition and bv the'means presently to be described, permitted todescend to the outlet chute 48 and thereupon, there being no key orcheck in the frame 35, said frame by means of the handle 12, disk 29.tooth 50 and dog 49, may be readily reversed in motion to perform acomplete rotation and ofthe time the frame 35 has performed a com- Leofeet the movement of the .bottom of the cylinder 16.

The means for holding the key or check 27 within the slot- 41 comprise,as hereinbefore described, the pivoted arm 45 and shoulder 46. The arm45 is secured by a screw or pivot 53 ,upon a lug extending laterallyfrom the inner edge of the frame 35, as clearly represented in Figs.i2and 3, and this arm 45 is spring-pressed to carry its longer memberinwardly through a lateral slot 54 in-said frame 35 so that the end ofsaid member may normally rest in a position in which it may co5peratewith the shoulder 46 in arresting a key or check or other tokenintroduced into the slot 41. At

plunger to the plete rotation and the predetermined quantity of gasolenehas been discharged from the cylinder 16, the arm 45' is turnedoutwardly' on its pivot 53 to release the key or check 27 and permit thesame to descend, and this releasing movement of the arm 45 is impartedto it by the front end of a pin 154 carried by a standard 55 whichisintegral with the frame 38 hereinbefore referred to. During the rotationof the frame to discharge a predetermined quantity of gasolene or thelike, the threaded sleeve 37 connected therewith rotates and effects thetraveling movement of the frame 38 in a direction toward the frame 35and atthe conclu'sion of this movement thefront end of the pin 154,engages the short member of the arm and turns said arm to carry itslonger member from the key or check 27, thus releasing said key or checkto descend.

7 The standard has upon its upper end a plate 56 which projectsfrontwardly and which, during the rotation of the frame 35 to dischargethe quantity of the gasolene, travels with the standard 55 and iscarried below the entrance slot 26, thus forbidding the entrance ofanyfurther key or-check to themachine at that time. During the reverserotation of the disk 29 and frame 35 to restore the slot 41 in saidframe to its initial position and effect the movement of the plunger 15in the cylinder 16 to its ini- 1 tial position, the frame 38 andstandard 55 travel rearwardly from the frame 35 and during such movementthe'pin 154' releases the arm 45 to take its initial position, and

- plete rotation in one direction has been performed, and a in 57carried by the standard 55 serves, y engaging a solid part of thecasing, to arrest the mechanism therein after the frame 35 has performedits complete reverse rotation.

The keys or checks 27 will be designative incharacter, as by shape orcolor or hearing some designation, such as a number or other device, andchecks bearing varying designations will indicate by such designationsthe respective individuals or employees to whom they have been or are tobe distributed and Whose duty it will be to operate the machine andaccount for the keys or checks intrusted to them. One system of usingthe machine would be to designate the individual employees by the samenumerals as those on the respective keys or checks intrusted to them,each employee receiving a set of checks for his special use and beingoompelled to account for the checks or for the value represented bythem. The checks or keys may not have a standard value, since theliquids to be sold or purchased will vary in value from time to time andalso vary in value in respect to, say, gasolene bringing one price andoil a different price.

The invention will be substantially understood from the foregoingdescription without further detailed explanation. One point of theinvention resides in the applicability of thefeatures of my invention tothe ordinary shaft 11 of a gasolene dispensing. apparatus, therebyavoiding the construction of special apparatus to accompany my inventionand rendering my invention more useful to the public in that it may bedirectly applied to apparatus already .in hand. When the shaft 11 is ofthe proper size to at once receive the casing 10 and frame 35, thesleeve 30 hereinbefore referred to will be omitted, and when the shaft11 is less in diameter than the bore of the frame 35 a sleeve 30 will beplaced thereon to. properly increase such diameter of the shaft. Whenthe frame 35 is in its initial position shown in Fig. 2 the key or check27 will be fed thereto and the disk 29 and said frame 35 given acomplete rotation in one direction to effect the discharge of thepredetermined quantity of gasolene, and thereupon the key or checkhaving been released to descend through the chute 48, the disk 29 andframe 35 will be given a complete reverse rotationin order to properlyset the plunger 15 in the cylinder 16 and cause the plate 56 to recedefrom below the entrance slot 26 and the pin 154 from the arm 45, theframe 35 becoming arrested in lot its initial position ready to receivea fur- 1 ther key, check or other token.

I desire it to be understood that my inven- 'tion is not limited to thedetails of construction hereinhefore described as illustrative of oneembodiment thereof. In carrylng out 1,135,251 v t it my invention in theform illustrated, utilize the known container 19, measure or cylinder l6and plunger 15, said cylinder and plunger constituting What may betermed a single acting pump, but I do not confine my invention to usewith any special style of pump so long as the main purposes of theinvention are carried into elfect.-
